摘要
软围岩断层巷道开采过程中易出现冒顶和顶板破碎的现象,给施工带来了极大的阻碍。东曲矿针对28208工作面断层附近软岩巷道的基本情况和具体地质构造,采用两端头支护及两巷超前支护技术,对机头、机尾的切顶、端头及两巷进行支护,并针对冒顶和顶板破碎提出了应对措施,取得了良好的支护效果,顺利通过断层附近软岩巷道。
The phenomenon of roof collapse and roof fracture is prone to occur during the mining process of soft surrounding rock fault roadway,which brings great obstacles to construction.Targeting the basic conditions and specific geological structures of the soft rock roadway near the 28208 working face fault,Dongqu Coal Mine adopted the support of both ends and the advanced support technology of the two roadways to support the cutting top,ends and the two roadways,and proposed countermeasures for the roof and roof fracture,which achieved good support effect.The soft rock roadway near the fault was successfully passed.
